The Write to Spreadsheet File is not the same as writing to Excel -- for that, you should use the Report Generation Toolkit (and there have been a number of posts here, as well as examples that ship with LabVIEW).
That being said, it is not clear (a) what you are trying to do, and (b) what is (or is not) happening. The image you attached looks OK ...

Write to spreadsheet file.vi is storing data in one row only.

The 8 points of data is going into one column in the spreadsheet. In the "Write to spreadsheet file string.vi" how do I write the 8 points to one row for each cycle?
I got this VI from NI's web a couple of years ago and forgot how to modify this part. I usume it is within the write file.vi.
Thank you in advance

I just reread your original post and the way the "Write to Spreadsheet File.vi" that ships with LV works by default is to put 1D arrays into rows. I read your post backwards and told you how to put the data in a column. Sorry.
In any case, perhaps you need to make sure the Transpose input ISN'T true, and that the delimiter IS a tab.

Help on fonction Write to spreadsheet file

Hello,
I come on this forum to find a solution for my issue.
I have made a VI which acquires an input voltage and where the user can modify some parameters.
For each iteration of my while loop, I want to save the data in a csv file that's why I'm using the fonction Write to spreadsheet file.
But when I want to use this saved datas in csv format with Excel, the data were saved in string format so not a numeric. My purpose is to have some numerical datas and not strings because I can't do graphics or calculs.
As you can see on the csv saved file, only the iterations of the while loop (column C) are in a numerical format.
Here is my problem, thank you in advance for your help

Looks like you're using regional decimal signs, try "%.;.3f" as format

If you want to copy files as fast as possible, without processing them (as the DOS "copy" or the Unix "cp" command), you can try the java.nio.channels package.
import java.nio.*;
import java.nio.channels.*;
import java.io.*;
import java.util.*;
import java.text.*;
class Kopy {
     * @param args [0] = source filename
     *        args [1] = destination filename
    public static void main(String[] args) throws Exception {
        if (args.length != 2) {
            System.err.println ("Syntax: java -cp . Kopy source destination");
            System.exit(1);
        File in = new File(args[0]);
        long fileLength = in.length();
        long t = System.currentTimeMillis();
        FileInputStream fis = new FileInputStream (in);
        FileOutputStream fos = new FileOutputStream (args[1]);
        FileChannel fci = fis.getChannel();
        FileChannel fco = fos.getChannel();
        fco.transferFrom(fci, 0, fileLength);
        fis.close();
        fos.close();
        t = System.currentTimeMillis() - t;
        NumberFormat nf = new DecimalFormat("#,##0.00");
        System.out.print (nf.format(fileLength/1024.0) + "kB copied");
        if (t > 0) {
            System.out.println (" in " + t + "ms: " + nf.format(fileLength / 1.024 / t) + " kB/s");
}

Using UTL_FILE i'm able to read csv file. I'm stuck up in appending some more columns to same csvYou'll struggle to append data to an existing CSV.
You'd be better to read the data from one CSV, and create another CSV using that data, and the extra data you want, and then when finished, delete the original file and rename the new file to the old filename.
You should be able to do that using External Tables to read the source file (easier than using UTL_FILE) and UTL_FILE to write the new file.

How we write into properties file using get class method

Hi
I want to set some value into properties file using given code
can any one please tell me how i can do this.
property file
setting.properties
Name     =     abc
and code I use is
java.io.InputStream oInputStream = this.getClass().getResourceAsStream("Setting.properties");
               Properties obj = new Properties();
               obj.load(oInputStream);
               String myName = obj.getProperty("Name");
               System.out.println("myName :"+myName);
               obj.setProperty("Name","def");
               FileOutputStream oOutput= new FileOutputStream("Setting.properties");
               obj.store(oOutput, "");
thanks.

You can't.
If you have properties that change dynamically, you should not be using a properties file that sits in the classpath, you should be using Preferences, or a properties file that sits in some application or possibly even user directory, but not one in the classpath. The proper way to do this, would be to have a properties file in your jar (or otherwise in your classpath) that contains the defaults, and another one outside of the classpath in one of the twwo above mentioned areas, then, you read the default one only if the other doesn't exist, or you read the default one first, then read the other overwriting the values from the defaults.
Don't forget to save the properties again (right after loading if you loaded, or always load, the defaults) after every change.

Save 2D array in write to spreadsheet file

Hello,
I want to save 2 signals coming from 2 channels in 1 file ( as a 2D file:
column 1 for signal coming from channel 1, and column 2 for signal coming from channel 2).
How I can do it?
See my example please. I can save these 2 signals on 2 different files. I
can not find a way to put them in on file.
Thank you so much.
Pascal

Since the output of AI Read is a 1D array of waveforms you have to extract the data of each waveform and create a 2D array in order to feed that to the Write to Spreadhsheet File VI:
You'll need to check on the transpose. Note that doing this will lose the timing information. You may want to use the Write LabVIEW Measurement File Express VI instead.
Also, any reason why you have a loop set to run just once?

How to get sql query data and write into csv file?

I am writing to seek help, in how can I create bat. script which can execute the following logic:
connection to the database
run sql query
create CSV file
output query data, into CSV file
save the CSV file
osql
-S 84.18.111.111
-U adw
-P rem
-i "c:\query.sql"
send ""
sed -e 's/,\s\+/,/g' MCI_04Dec2014.csv > localNoSpaces.csv
-o "c:\MCI_04Dec2014.csv"
This what i have so far, and I am little struggling with the logic after creating CSV file. I am unable to get the above script to work, please advice further, where I may be going wrong.
Can you create if statement logic within window's script, to check for null parameters or data feeds?
Any hints would be most appreciated.

Thank you for your reply.
Apology for posting the code irrelevant to the forum, as I am still novice scripting user.
My goal is to create window's script which can compute the above logic and send the final output file (csv), to FTP folder.
Can this logic be implemented via bat. script, if so, is there a example or tutorial i could follow, in order to achieve my task.
Any help would be much appreciated.

在定义路径时有两个路径框,一个是FILE PATH,另一个是NEW FILE PATH,请问我应该定义哪个呢???定义好后就可以直接往spreadsheet file.vi中存储和读取记录了吗???还需要再做任何其它的工作吗???谢谢...

定义file path就可以了，new file path 是这个VI的输出

Error 6 occurred at Open/Create/Replace File in Write Spreadsheet String.vi- Write To Spreadsheet File (string).vi- Untitled 1

Hi I'm getting the above error when attempting to get a file path control to write to a spreadsheet vi?
The spreadsheet is opened in open office but saved as a .xls in the documents folder.
The spreadsheet only contains one row and three columns each with text contained but when I run the VI and then open and view the actual speadsheet all three headers appear together in the A1 cell before the title error message appears.
Is Labview not compatible with open office? Perhaps someone can confirm if this is indeed the case?
Thanks in advance...

Solved. One just needs to click seperate by tab in the import dialog than opens in OO calc.

Write into existing file with "write to text file"

Hi all,
I have a text file that contains several lines of data (text). Now I would like to replace the first three lines with text coming from a string array.
My approach is shown in WriteToFile.vi that is attached.
When I am executing this vi (with an empty file), everything seems to be working fine in the first place.
The file will contain the following text:
oneoneone
twotwotwo
threethreethree
Now, when the third element in the array is shortened (lets say to "threethr") before execution, the file will contain the following text:
(the file was not emptied before execution)
oneoneone
twotwotwo
threethr
three
How can I avoid the last line being written? I have made many tests and I could not find a solution.
One more example:
Lets say we have an existing file, inside this file is:
oneoneone
twotwotwo
three
fourfourfour
Now I would like to overwrite line three with "threethreethree". Therefore I execute my vi as shown in the attachment.
What I get as a result is:
oneoneone
twotwotwo
threethreethree
ur
So, the text in line four, which should not be touched, is "ur" instead of "fourfourfour".
Any idea to solve this problem?
What I basically need is replacing a line of a text file in a conveinient way.
Thanks,
Holger

The remaining fourth line is there because the third line has a <nl> at the end. You have not emptied the file so the rest of the file will be kept. This is because your line is shorter.
In the scond example the third line is longer and it will overwrite the beginning of the fourth line.
Files aren't organized in lines they are oganized in bytes. And what you write are bytes to the file even with text files.
Replacing a single line in a file is done by reading the file line by line. All unchanged lines are written to a temporary file and the line with the new text will be written instead of the original line to the temporary file. When the writting is done rename the original file, then rename the new file into the original file and then delete the renamed original file.
